  `(require 'qp)'

When displaying error messages and warnings, it is paramount that the
output generated for circular lists and large data structures be
limited.  This section supplies a procedure to do this.  It could be
much improved.

     Notice that the neccessity for truncating output eliminates
     Common-Lisp's Note: Format from consideration; even when
     variables `*print-level*' and `*print-level*' are set, huge
     strings and bit-vectors are _not_ limited.

 - Procedure: qp arg1 ...
 - Procedure: qpn arg1 ...
 - Procedure: qpr arg1 ...
     `qp' writes its arguments, separated by spaces, to
     `(current-output-port)'.  `qp' compresses printing by substituting
     `...' for substructure it does not have sufficient room to print.
     `qpn' is like `qp' but outputs a newline before returning.  `qpr'
     is like `qpn' except that it returns its last argument.

 - Variable: *qp-width*
     `*qp-width*' is the largest number of characters that `qp' should
     use.
